I propose revising 3.6.2 to be a user option rather than requiring it to
be always on. I include two possible rewrites below.
UAAG20 3.6.2 currently reads:"3.6.2 Preserve Distinctions: When rendered
text is rescaled, distinctions in the size of rendered text are
preserved (e.g., headers continue to be larger than body text). (Level A)"
This actually conflicts with other guideline documents that actually
recommend that the user have the option to display all text in the same
font, including uniform size. Here are two examples from ISO 9241-171
item 10.3.2:
EXAMPLE 1 A word processor contains a "draft mode" which shows
all document text in a single, user-selectable font, colour and
font-size, overriding any formatting information specified in the
document itself. When the user encounters small text that they have
difficulty reading, they can switch into this mode and will still be
viewing the same section of the document, but at a size they have
already selected as meeting their needs.
EXAMPLE 2 A user has difficulty reading small text on the
screen, so they set a "minimum font size" preference valuein the
operating system's control panel. The Web browser respects this
setting and automatically enlarges any text that would otherwise be
smaller than this size.
Here are two possible rewrites:
"3.6.2 Preserve Distinctions: /The user has the option that /when
rendered text is rescaled, distinctions in the size of rendered text
are preserved (e.g., headers continue to be larger than body text).
(Level A)"
"3.6.2 Preserve Distinctions: /The user has the option to preserve
distinctions in the size of rendered text when that text is rescaled
/(e.g., headers continue to be larger than body text). (Level A)"
The first merely prepends the stock phrase "The user has the option".
Unfortunately the document only use the variations "The user has the
option TO" and "The user has to option OF", neither of which would fit
the rest of the sentence, so I had to introduce "The user has the option
THAT". The second is revises the wording more thoroughly in order to use
the already-used variant "The user has the option TO". I actually prefer
the second, but either would be acceptable.
Thanks,
